ANTICREEPEB.

Specification of Letters Patent. Patgnted J 15, 1920 Application filed. November 5, 1918,5eria1' No. 261,185. Renewed September 11,1919. Serial No. 323,128.

To all/whom it may concern:

Be it known that I, Ins T. Hownnn, a citizen of the UnitedStates, residing in the town of Nappanee, county of Elkhart, Indiana, have invented certain new and useful Improvements in rinticreepers, of which the following is a specification.

' My invention relates to improvements in anticreepers or rail anchors for railroad rails.

The principal object of my invention is to provide a. most effective anticreeper which may be readily applied to av rail base and which is most efficient in resisting rail movement, and one which maybe readily removed from the rail without impairing the efficiency of the anticreeper. Another object of my invention is the production of an anticreeper which is secured to the railroad rail by an improved wedge member having a yieldable, serrated detent connection with the ai'iticreeper, whereby a rigid grip on the rail .is effected and any retrograde movement of the wedge member effectually prevented. Other and collateral objects of my invention are mentioned and described hereinafter.

The preferredembodiment of my invention. is illustrated in the accompanying drawing in which Figure lis an elevation of a rail in section showing my 1113811131011 2 1s a plan view showapplied thereto; Fig. ing a fragment of a rail with my invention applied thereto Fig; 3 is a section taken on the line 33 of Fig. 2; Fig. 1 is a section taken on the 1inel-1 of Fig. 3; Fig. 5 is a side elevation of the wedge member; is a bottom plan view of the wedge; Fig. is a top plan view of the wedge; and Fig. is a fragment of the anticreeper body showing the wedge chamber formed therein.

Similar nume *als of reference indicate like members and parts of members throughout the several views on the drawing.

On the drawing the numeral 1 indicates a railroad rail having the usual base flange 2, and numeral 3 indicates an anticreeper body arranged beneath the rail base flange and provided with the hook member 1 adapted to engage one edge of the rail flange. Numeral 5 indicates a stop lug depending from the body of member 3 and adapted to engage the rail tie 6 to prevent longitudinal rail movement. The numeral 7 indicates a jaw member formed on the opposite end of the member 3 and having an overhanging wall section 8 to form the wedge chamber 9, said chamber being adapted to receive the locking wedge, as hereinafter described. The wedge chamber is provided with the upright wall 10 which is inclined angularly with respect to the edge of the rail flange 2, the same chamber having a series of serrations or teeth ll formed or provided on the under surface of the jaw wall 8 and extending, as a series, longitudinally thereof. As indicated in Fig. 3 of the drawing the *all. surface upon which the serrations 11 are formed is somewhat inclined downward toward the edge of the rail base flange. The numeral 15 indicates a wedge detent member mounted upon said wedge at its forward or smaller end, the bent over portion 16 whereof is secured to the under side of the wedge portion by a lug or hook 17 arranged in a suitable recess in said wedge member to prevent longitudinal displacement of the detent member from the wedge body. The

detent member 15 is preferably made of springmetal and provided on its upper sur face with the teeth or serrations 18 which are preterably graduated in size from the smallest formed adgacent the detent end 16 which wedge is provided to the largest at theopposite or rear end thereof, said detent member normally extending angularly from its mount on the wedge.

In operatiomthe wedge 12 carrying the detent 15 is driven into the wedge chamber 9, the teeth 18 of said detent successively engaging several interstices of the teeth 11 on the wall 8 until driven home, the detent member 15 yielding downward as deeper penetration of the chamber 9 is effected, the tooth engagement between said detent and the serrated wall 8 being always maintained by the upward thrust of the spring detent 15.

I claim:

1. In an anti-creeper, the combination of a yoke member adapted to extend around a rail base, wedging means'comprising a rigid member and a separate piecedetent member, the latter being suspended at one end thereof and extending longitudinally of the rigid member; and a complementary serrated connection between said detent and a said rigid member.

tween said detent and yoke members.

3. In an anti-creeper, the combination of ayoke member adapted to extend around a rail base, wedging means intervening be tween the yoke and the rail said wedging 1 means comprising a rigid member and a 'yieldable detent member, the latter Vintervening between the rigid member and the yoke, said detent member being provided with means connecting it with-one end of.

said rigid member; and a complementary serrated connection between said detent and said yoke member.

4. In an anti-creeper, the combination of:

a yoke member adapted to extend around a rail base, wedging means intervening between the yoke and the rail said wedging means comprismg a rigid member and a yieldable' detent member, said detent member being connected with the rigid member adjacent one end of the former and yieldable from said point of connectiongand a complementary graduated serrated connection between said detent and yoke members.

5. In an anti-creeper, thecombination of a yoke'member adapted to extend around a "rail base, said yoke being provided with a wedge chamber, wedging means carried in said chamber and intervening between the yoke and the Ittll, said wedging means comprising a carrier member and a separate piece detent member mounted upon said carrier member, said detent member intervening between said carrier member and said yoke chamber; and a complementary serrated connection between said detent and said chamber.

6. In an anti-creeper, the combination of a yoke member adapted to extend around a rail base, wedging means comprising a rigid member and a detent member intervening between the rail and said yoke,'said detent member being hooked 'over the end of said rigid member and yieldable therefrom; and a complementary serrated connection be tween said detent member and said yoke.

7. In an anti-creeper, the combination of a yoke member adapted toextend around a rail base, wedging means intervening betweenthe yoke and the rail saidwedging means comprising arigid member and a yieldable detent member, the latter intervening between the rigid member and the yoke, said detent member being provided with means connecting it with one end of said rigid member; and a complementary graduated serrated connection between said detent and said yoke member.

8. In an anti-creeper, the combination of a yoke member adapted to extend around a rail base, resilient wedging means intervening between said yoke and the rail, and a complementary serrated connection between said wedging means and said yoke, said serrations being graduated in size, which serrated connection is adapted to facilitate the operation of said wedging means. 7

9. In an anti-creepeig the combination of a-yoke member adapted to extend around a rail base, resilient wedging means intervening between one end of said yoke and the rail, and a complementary serrated connection between said wedging means and said yoke, said serrations being graduated in size, which serrated connection is adapted to facilitate the operation of said wedging means.

In testimony whereof I have hereunto at fixed'my signature this 18th day of October, 1918.
